Dear MediaWiki experts,
I cannot really figure out the behaviour of MediaWiki regarding thumbnailing. What I want to achieve is that my MediaWiki installation produces thumbnails in a specified size.
What I did after reading through several help pages is this: --------------------------- # Images und Thumbnails $wgThumbLimits = array( 80, 250, 390 ); $wgDefaultUserOptions['thumbsize'] = 1; // thumb size 250
$wgImageLimits = array( array( 80, 90 ), array( 800, 600 ), array( 1280, 1024 ) ); $wgDefaultUserOptions['imagesize'] = 2; // image size 800, 600 ---------------------------
In my opinion this should guarantee that for every image uploaded, there is an 80, 250 and 390px sized thumbnail. In many cases this is true, but there are some cases were I can find a 100px thumbnail, but no 80px thumbnail.
If I understand it correctly, this can perfectly be the case if any user sets his/her preference to 100px. I don't mind so much extra sizes to be produced, but I want to make sure that a 80px thumbnail is there.
Maybe in the cases where it is not present the images were uploaded before the above mentioned setting was made? But how can I get the wiki to redo thumbnails in my desired size?
cheers, Bernhard
